Welcome to Windows 7 Forums. Our forum is dedicated to helping you find support and solutions for any problems regarding your Windows 7 PC be it Dell, HP, Acer, Asus or a custom build. We also provide an extensive Windows 7 tutorial section that covers a wide range of tips and tricks.

You may want to download Coretemp64 or realtemp to keep an eye on the CPU temps. see if you can determine at what temp the fan starts and the temp it cuts off. It may give you an idea whether the fan is doing what it is designed to do or whether it is malfunctioning. It can also give you needed info if you call the manufacturer.

You say it's only 3 months old (& probably still in warranty?) so if it was me I wouldn't be flashing a BIOS for this stage. Also, I wouldn't expect dirt and dust to accumulate badly in 3 months...but who knows.

I'd have a look in the BIOS or any fan control program that came with the PC. My ASUS motherboard has a brickwall fan control option called "Stable" which cycles the CPU fan from 50% to 100% at a specific temperature. I can't say I'd ever use it but sounds similar to what you are hearing.

On laptops with dedicated graphics and an Intel i-series mobile processor there is "switchable graphics" capability. When on battery power the system will switch automatically to the low power Intel graphic engine contained on the i7 Sandy Bridge chip. When plugged in the system will switch to the dedicated nVidia graphics chip (if you are doing something that requires more processing power).

So my guess is that the issue has something to do with your graphics system.
The first question is "are you doing anything notable that results in this behavior (like playing a video game), or does it occur immediately and constantly? You are looking for clues.

If constant it brings to mind issues people have with certain graphics drivers that have caused these kinds of overheating/fan issues. Updating or rolling back the driver was shown to correct the problem. Something you might consider.

A word of caution: These switchable graphics systems often use a "tandem" driver package available only on the laptop manufacturer's website. These contain both the Intel and nVidia drivers together. People have screwed their systems up when trying to install a stand alone driver from nVidia alone. So check and be sure of what you can and can't do. And most certainly create a System Restore Point before attempting any changes.

You could also play with your W7 power settings. Go to Control Panel > Power Options and in the left column choose " Create a Power Plan". Then use the new plan to change settings to see if they have any effect.

Laptop fan goes up, then down, then up, then down . . .
